The classification of limb paralysis is related to its location, as follows: 1. hemiplegia: often occurs after cerebral hemorrhage or cerebral infarction, manifesting as restricted movement of the contralateral limb; 2. monoplegia: often occurs after unilateral nerve compression, manifesting as restricted movement of the unilateral limb; 3. paraplegia: often occurs after spinal or spinal cord injury, manifesting as sensory, diaphoresis and vegetative nerve dysfunction. If a patient has the above symptoms of limb paralysis, he/she should go to the hospital in time for relevant examination and be given targeted treatment by a professional doctor to avoid prolongation of the disease.
